certain new and useful linpro'vements in Extensionlables. of which the following is a full, clear. and exact description. reference being had to the accompanying drawings. forming a part hereof.

My invention has relation to iniprovernents in extension-tables; and it consists in the novel construction and arrangement of parts more fully set forth insthe,

v specification and pointed out in the clailns.

In the drawings. Figure a top plan of the table extended. with parts broken away; Fig. 2 is a top plan oi the table in folded position. with parts broken; Fig.

3 is a side elevation oil ig. 1; Fig. l is a side elevation of Fig. 2; Fig. 5 is a longitudinal vertical section on line 5-5 of Fig. 1; Fig. 6 is a' vertical longitudinal section online 6-43 of Fig. 2'; Fig. 7 is an enlarged vertical transverse section on line 7-7; of Fig. 1; Fig. 8 is a sectional detail on line 8-8 of Fi 3, and Fig. 9 is a sectional detail on line 99 of Fig. 7. I

The object of my invention is to construct a table which may be folded or extended by a single movement in proper direction, of the extensible section or leaf thereof, the. parts being capable oi operation from either end of the table.

follows:

A further object is to make suitable provision for housing the extensible sections or leaves within the table and without the necessity of disturbing them from their permanent supports.

The advantages of the invention will be better apparent front a detailed description thereof which is as Referring to the drawings, B, represents the body of the table and L, the logs thereof as usual. The center section or top of the table is represented by 1. and the extension leaves or sections by 2, 2. the meeting edges of the-sections being beveled as shown to facilitate the inward movement of the leaves 2. and [0 effect a better joint when the parts are extended. To prevent lateral displacement of the top 1, the same is provided with depending side wings or guide brackets 23, 3, which 'bear against the faces of the body or frame B. The bottom of the section 1 has a reinforcing panel l as shown. -Secured to the under surface of each leaf 2 are a series'of parallel straps 4, 4, the side straps terminating at their outer ends in finger-holdsor hooks 5, ancl being slightly shorter than the middle strap. The inner terminals'of the middle strap are pivotally coupled to I the adjacent ends of a toggle-frame '1 whose center is transverse member has recesses 1' cut in the 16 thereof opposite the side straps 4, the serving:

extensions of the side straps 4,- said runners loosely through notches a cut in the member 6 abov' 10'secured to the under surface of the pencil. The

.folded so that no accidental displacement of the parts is possible.

be folded or closed as shown in Fig. 2, the operator seizes the hooks 5 and pulls the adjacent leaf 2 toward him. This at once expands or unfolds the toggle frame T, in which unfolding the opposite leaf 2 is simultaneously forced outwardly.

.When the table is,in its iolded occupy a position under the top or section 1, and the for theiree passage of the leaves thereunder, until the rollers 9 settle inthe depressions a, as clearly obvious from the drawings. When the parts are pulled out, the runners of course are likewise pulled outwardly, and

pose the operator pushes one of the leaves inwardly. This will at once contract or fold the toggle-frameand the opposite leaf will be simultaneously retracted or drawn inwardly until the limit of the contraction of the toggle-frame is reached, by which time, the rollers 9 riding over the runners 8 will settle themselves on the shallow depressions apthe comparative shallowness of said depressions serving to hold the top or section 1 sufliciently elevated to allow for the leaves 2, 2, to pass under it. (Fig. 6). By this time the interlocking be tween the angle-pieces 11, 12 will have taken place and ing the leaves 2 inwardly, the bevel contact between a edge tosupport the rollers 7, 7. These rollers serve support the bars or runners 8, ,8, forming the reai'f the recesses r. Theupper edges of the runners 8 area guided by the rollers 9.mounted in the forked brackpts runners 8 though forming extensions of the straps 4] The operation of the table is apparent and may: be briefly adverted to as follows: Assuming the table'to position, the leaves 2 rollers 9 rest in the shallow depressions a of the runners 8. In the folding of the table, the unnotched portions 1 of the runners hold the center top sufiicien'tly elevated (Fig. 5), bringing the parts 1 and 2, 2, to the same plane} Again, assuming the table to be extended, (Fig-5) sup;--

' thorn and the section 1 enables such inward movement a to receive the rollers 5).

ing angle-pieces 12 on the leaves 2 when the partsare i in the unfolded position of the parts, the rollers 9 settle themselves in the deeper depressions a of the runners the table is folded to its smaller dimeflsions. In startto be accomplished with minimum resistance, the leaves 2 Wedging themselves under the top 1 and orcing the runners 8 under the rollers 9 by which the center 1 is virtually supported. The depths of the depressions a, a are so proportioned thatovhile' the shallow depressions a' permit the top '1 to be elevated sufficiently to allow the leaves 2 to pass under it, the depressions a 'allov vlthe top 1' to drop to a plane even with the leaves 2 when the latter are Withdrawn.

Having deseribed my invention what I claim is:

1. A table co mprlslng a center top or section, terminal leaves, runners extending inwardly from the leaves under the top, supporting brackets on the top resting or? the run ners, suitable formations on the runners for elevating the top sufliciently .to permit the leaves to pass under the top, the runners having formed thereon suitable depres l of the table and having its ends pivolally secured to the leaves, runners extending inwardly from the leaves and supported beneath the table, roller-brackets connected to the center top and resting on the runners in a plane eon forming to the plane of disposition of the leaves for a retracted position of the latter. and formations hn the runners for retaining the top in an elevated plane for the folded position of the table'\'.'hereh v the. leaves are znhipled to pass under the top, substantially as set forth.

3. A table comprising :1 (enter Iop or section, (erlhinnl leaves, a toggleiranie having a fixed axis at the renter of the table and having its opposite ends pivotnllv ronplod to ihk leaves, runners-or bars extending inwardly from the leaves beneath the table, supporting rollers for the runners, roller brackets dependim; from the renter top and resting on the runners, the upper edge of the runners beiig provided with shallm' and deep depressions spared a suitable distanee apart for the reception of the rollers of [he rolier-ln-nekei's, the unnotehed portions being adapted to hold the center top suilieicntly elevated for the fre passage of the. leaves thereunder, the shallow depressions allowing the top to ('(llllO in close conlzn'l \vilh llll' loaves .in their closed position and the deep depressions allowing the center top to drop lo a plane even with the lQzIVr'r; in.
